First off; I love your implementation of Endergy's suggestions! Thank you so much for bringing this to life!

Second; is it possible to implement bone meal behaviour similar to vanilla grass growth? I.e. using bone meal on stygian grass will cause a patch of stygian long grass to grow on nearby stygian grass blocks, perhaps including the growth of enbiotic plants?

Third; is it possible to allow stygian grass to spread to nearby end stone the same way grass spreads to dirt?

your suggestions are added in my fork(indev) : https://github.com/quentin452/enderoni-continuation
